| IC revision | B |
Description
The TAS3251 Ultra-HD audio evaluation module demonstrates the TAS3251 integrated circuit from Texas Instruments. TAS3251 is a digital-input, high-performance Class-D audio amplifier that enables true premium sound quality with Class-D efficiency. The digital front-end features a high-performance Burr-Brown™ DAC with integrated DSP for advanced audio processing, including SmartAmp and SmartEQ. The integration of this single-chip solution reduces overall system solution size and cost. The DSP is supported by TI PurePath™ Console Graphical tuning software for quick and easy speaker tuning and control. The Class-D power stage features advanced integrated feedback and proprietary high-speed gate drive error correction for ultra-low distortion and noise across the audio band. The device operates in AD-mode and can drive up to 2 x 175 W into 4-Ω load and 2 x 220W into 3-Ω load.
Features
- Stereo, Mono, and Two-way speaker configurations
- Audio Inputs: USB, Optical SPDIF, COAX SPDIF, Direct I2S or TDM
- Audio Sample Rates: 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz
- Works with PurePath™ Console 3 for advanced tuning
- Double-sided, plated-through, 2 oz. Cu 2 layer PCB layout
